Current status of vasectomy reversal.

Area of Science:

• Urology
• Reproductive Medicine
• Microsurgery

Background:

• Vasectomy reversal is the primary microsurgical treatment for male infertility.
• It has evolved into a sophisticated, minimally invasive, and cost-effective procedure since its introduction in 1977.
• It restores physiological fertility in over 90% of men.

Purpose of the Study:

• To review the efficacy and advancements in microsurgical vasectomy reversal.
• To compare vasectomy reversal with assisted reproductive technologies (ART).
• To discuss the timeline of fertility recovery and emerging techniques like robotic reversal.

Main Methods:

• Review of microsurgical techniques for vasovasostomy and vasoepididymostomy.
• Comparison of vasectomy reversal outcomes with ART.
• Discussion of factors influencing fertility recovery, such as time since vasectomy.

Main Results:

• Microsurgical vasectomy reversal is highly efficient, cost-effective, and restores fertility in >90% of cases.
• ART is a costly alternative with no proven higher cumulative pregnancy rates.
• Fertility recovery can take up to 2 years, especially after long-standing vasectomy, with ART as a potential bridge.

Conclusions:

• Microsurgical vasectomy reversal remains a gold standard for treating male infertility post-vasectomy.
• Continuous technical innovations are enhancing the procedure, particularly for vasoepididymostomy.
• Robotic vasectomy reversal is emerging, but its efficacy compared to conventional microsurgery requires further evaluation.
